[Intrapartum fetal monitoring by electrocardiography].
To study the diagnostic values of intrapartum fetal electrocardiography (FECG) and cardiotocography (CTG), 68 patients in labor were monitored at random. One-min Apgar score was chosen as the gold standard. The specificity (87.1%) and accuracy (86.8%) of FECG were found better than those of CTG (54.5% and 57.4% respectively). Fetal hypoxia and acidosis was firstly manifested by shortened P-R interval, FHR deceleration and increase in the T wave amplitude. It suggested that FECG can be a reliable diagnostic method following CTG screening.
